Theoretical studies on the effects of atmospheric turbulence in the infrared (IR) spectra can be found in the literature [1]}, [2]}, [3]}, [4]}. For example [1]} proposes the Fried coherence diameter as a measure of the optical transmission quality through the turbulent air, which reflects the relation of wavelength and imaging quality. According to this measure, as the wavelength increases, the resultant effect of turbulence tends to decrease. Therefore, the visible spectrum suffers more than the IR spectra from turbulence. However, the effect of turbulence on images also becomes significant in the IR spectra, when the refractive index structure parameter, \({C_n}^2\)  [1]}, [7]}, and the path length are sufficiently high.
